Q: Since installing Sierra, trackpad stuck on slow
I upgraded to macOS Sierra yesterday, and since then the tracking speed has been stuck on slow. Adjusting the speed in System Preferences by moving the slider to 'fast' does nothing, and if I exit and re-enter System Preferences and check again the slider has returned to 'slow'. It does not appear to be a problem with my trackpad, as in Accessibility I can successfully set my scrolling speed to fast. Has anyone else encountered this problem?

Have the same MacBook Pro. Have you tried safe mode or a test user to see if you still have the same issues?
